4 Claims.

This invention relates to an improvement in dust mops or similar articles of the character shown in my United States. Patents Nos. 1,993,336 and 1,996,056, and particularly to a means by which the mop may be vigorously shaken or vibrated to cause the accumulated dust and dirt to be dislodged and if desired, directed into a receptacle or on to a paper.

The object of the invention is to provide a mechanism of simplified construction and of iew parts whereby a rapid, vigorous vibratory -movement may be imparted to the mop head causing it to effectively shake the dust and dirt from the mop strands. l

A further object of the invention is to provide a mechanism of the character described having all of its operating parts fully enclosed and thereby having no projecting parts or elements likely to come in contact with furniture and do damage to the same during the moping or shaking operation.

A further lobject of the invention is to provide a fully enclosed shaking mechanism whereby the operating parts may be easily lubricated and protected and which by reason of this and their sturdy construction will provide a long life oi usefulness to the device.

In the accompanying drawing wherein several embodiments of the invention are shown, Fig. l is a side elevation of a mop with the lower portion thereof in section to show the shaking mechanism; Fig. 2 is a sectional view on the line 2-2 of Fig. l, looking in the direction of the arrows; Fig. 3 is a sectional view on the line 3-3 of Fig. l, looking in the direction of the arrows; Fig. iis a perspective View of the two coi-operating halves of the mop head frame; Fig. 5 is a sectional view through the mop and one of the halves of the mop head frame; Fig. 6 is a side view, partly in section, of a modified mop shaking structure; Fig. 7 is a sectional View of the structure shown in Fig. 6, said sectional View being taken at right angles to Fig. 6; Fig. 8 is aside elevation with parts in section of a modified structure; Fig. 9 is a side elevation, partly in section, of anotherr modied structure; and Fig. l is a sectional view through the structure of Fig. 9 at right angles thereto. i

Referring to the structure disclosed in Figs. l to inclusive, the mop stick or handle is shown at i I and has its lower end securely fastened by bolts, screws or rivets I3 in a boss I2 forming a part of a housing I 4. As will be seen in Fig. 3, the housing consists of twosimilar halves suitably secured together. Rotatably mounted within the housing is a segmental gear I5 which is secured on the shaft I6 mounted in bearings Il formed on the two halves of the housing it. Said shaft I l protrudes through the housing I4 and its yends project outside of the housing as clearly shown in Fig. 3. These projecting ends of the shaft I6 are formed with transverse holes which receive the vertically disposed ends I8 of the mop frame section I9 (see Fig. 4). Each of said mop frame sections is preferably made of a single bent section of substantially heavy wire or rod and comprises a` pair of vertically spaced parallel legs 20, each of which has one of its ends bent or inturned toward the other leg 20, as

' indicated at I8. At their opposite ends the members 2E) are connected by the integral vertical struts 2 I The vertically bent ends I8 fit into the holes in the shaft I6 and may be held therein either by the resiliency of the frame I9 or may be welded or otherwise secured to the shaft I6. When the two halves` I9 of the mop frame are in position as shown in Fig. 3, they are spaced apart at the front end of the mop as indicated at Z2 in Fig. 3 so that the mop may be easily slid in position through this opening. When, in position, the mo-p forms a substantially triangular arrangement, as clearly shown in Fig. 3.

In the drawing, a double-faced mop is shown, consisting of two; tuited sections 23 held together by the tapeor binding liwhich forms a pocket 25 into which the frames I9 fit as clearly shown in Fig. 5. A single-sided mop of conventional form may also be used.

The segmental gear I5 meshes With and is actuated by a similar, but slightly larger, segmental gear 26 mounted upon shaft 21 rotatably mountedin the walls of the casing I4. Segmental gear 25 meshes with and is operated by a rack 28 formed at the end of actuating rod or bar 29 which is vertically reciprocal in a longitudinally extending groove 30 formed in the stick II. A guide roller 3| mounted in casing I4 rotates4 against the outer surface of the rack 28 thereby holding it in constant mesh with the segmental gear 26. Through the arrangement disclosed it will be obvious that when the actuating rod or bar 29 is reciprocated up and down in the groove 30, it will oscillate the gear 26 causing the same vto oscillate gear I5, thereby vibrating or rapidly oscillating the mop frame sections I9 to shake the mop and dislodge the dust and dirt therefrom. The means for so reciprocatingr the bar 29 comprises a sleeve 3l surrounding the handle I I and movable thereon and secured to the upper end of the bar 29. The upper end of the bar' 29 is formed with a laterally bent end 32 entering into the sleeve 3|, which is preferably made of wood, and thereby attaches the sleeve to the bar 29. Bumpers or stops 33 of rubber or other material are secured in properly spaced relationship on the stick II, to restrict or limit the sliding vmovement of the sleeve 32 during its reciprocation.

It will be noted that the entire operating vmechanism is enclosed so that possibility' of damage to furniture and household equipment is prevented. That is to say, the gears and other mechanism, including the lower rack portion of the operating bar 29 are all completely enclosed and confined within the housing i4. The operating bar 29 is also movable within its groove.

so that the finished mop presents a smooth and symmetrical appearance. It will be noted that two segmental gears i5 and 26 are employed rather than one because it is necessary to keep the lower end of the housing elevated or above the floor during the mopping operation and this could not be done if the mop frame were, for example, secured to shaft 21 rather than to shaft I6.

In Fig. 6 a somewhat similar construction is shown except that an additional gear is used in order to secure a more symmetrical housing for the gears. There, the housing is shown at 30 and it contains two superimposed meshed gears 3l and 32. The lower gear is mounted upon shaft 33 which has its ends projecting from the casing as clearly shown in Fig. 7, these ends receiving the mop head frames I9 in the manner described in respect to the structure of Figs. l to 5 inclusive.

The upper gear 3l rotates upon the shaft 35i and said gear 3l is attached to a pinion 35 engaged by the rack 28 formed on the end of actuating bar 29, as described with respect to the structure of Fig. l. It will be obvious that as bar 29 is reciprocated up and down, it will through the gearing described, oscillate shaft 33 to thereby vigorously shake the mop mounted thereon.

In Fig. 8 is shown a casing iii constructed similarly to that described in'Fig. l and secured to the mop stick I! in the same way. Casing 4t contains two sprockets M and 42, spaced apart and connected by a chain @3. The lower sprocket 42 has a shaft i4 projecting outside of the casing and secured to the mop frames i9 in the manner described in connection with shafts I6 and 33. The lower end of the actuating bar 29 is inwardly bent or off-set at l5 and said end is pivotally attached at 55 to one of the links of' f the chain. In this construction, it will be apparent that as the actuating bar 29 is reciprocated up and down by movements of the sleeve 3l, it will move the chain i3 back and forth over sprockets 4l and 42 thereby .oscillating shaft Ml and vibrating the attached mop frame and mop in a manner similarto that previouslydescribed with respect to the structures of Figs. l and 6.

In Fig. 9 is shown a casing t@ similar to that described with reference to Fig. 8. Mountedin the casing are spaced pulleys 513 and El, the lowermost pulley 5l being mounted upon shaft 52 which is attached to the mop frames IQ in the manner previously described. The upper pulley El) is mounted either on a rotatable shaft 53 or mounted to rotate on a Xed shaft. Pulleys 5i) and 5I are connected by a drive cord o-r cable 54. The lower pulley 5I is double-grooved as clearly shown in Fig. 10, to permit sufficient oscillatory movement of shaft 52. The ends of cable or cord dengaging the grooves in the pulley 5l are attached in said grooves. The reciprocating bar 29 has its lower end operating within the casing M) and attached at 55 to the cc-rd 5. With the structure of Figs. 9 and 10, it will be obvious that as the bar 29 is reciprocated up and down in the groove 36, it will move the operating cord or cable 54 over the pulleys 5i) and 5i to thereby o-scillate the pulleys and cause shaft 52 to rapidly shake the mop to dislodge the dust and dirt accumulated therein,

In the various embodiments of the invention herein described, all of the operating parts are enclosed and protected. This is particularly true of the actuating bar 29 whichhas its lower end confined and movable within the casing so that this lower end cannot through vigorous operation l of the bar engage mop strands or otherparts of the mop to damage the mop and is also prevented from striking against or in any way damaging furniture or parts of the home.
